👉 The Perth Flu, also known as the 1918 influenza pandemic, was a particularly severe global outbreak of the H1N1 influenza virus that occurred between 1917 and 1918. It is often referred to as the "Spanish Flu" due to the lack of accurate reporting from Spain, where the pandemic was first reported. In Australia, including Perth, the flu had a devastating impact, causing widespread illness and high mortality rates. The Perth Flu was notable for its unusually high death rate among young adults, a characteristic that set it apart from typical influenza outbreaks. The virus spread rapidly due to close living conditions and limited medical interventions at the time, leading to significant societal disruption and a profound impact on public health infrastructure.
